Problem using st.exe to push data off to tape

[Julian Wolfe]

I'm trying to use John Wilson's ST.EXE program for DOS to push data off to
magtape on my Qualstar 1260S connected to an Adaptec 2902, but it stops with
a media error on every tape I try. Here's what I have done:

 

-          Created a DOS boot disk with only the aspi8dos.sys driver loading

-          Defined my TAPE variable as SCSI5:

 

The tape files and st.exe are stored on a fat16-formatted IDE drive.  That
is all that is on there, and the disk was freshly formatted.

 

Here's what happens when various commands are issued:

 

-          st iput filename.ext 512 - tape goes back and forth then stops
with a media error

-          st write - tape goes back and forth and then goes back to a dos
prompt.  I try to do 'st rew' after this, but then it does what looks like
the 'write' operation

-          st weof - "on line" light blinks continuously.  This doesn't
always happen, sometimes it does the 'st write' behavior.

 

So, thus far, I have no boot tapes.  Can anyone help me out with this?

 

Thanks
